| Apache Arrow |
| ============ |
| |
| Apache Arrow is a development platform for in-memory analytics. It contains a |
| set of technologies that enable big data systems to process and move data |
| fast. It specifies a standardized language-independent columnar memory format |
| for flat and hierarchical data, organized for efficient analytic operations on |
| modern hardware. |
| |
| The project is developing a multi-language collection of libraries for solving |
| systems problems related to in-memory analytical data processing. This includes |
| such topics as: |
| |
| * Zero-copy shared memory and RPC-based data movement |
| * Reading and writing file formats (like CSV, Apache ORC, and Apache Parquet) |
| * In-memory analytics and query processing |
| |
| **To learn how to use Arrow refer to the documentation specific to your |
| target environment.** |
